Vermont Gage 112309750 Class Zz Plus Plug Gage 9.75mm

Product Description

The VERMONT GAGE 112309750 is a Class ZZ Plus plug gage machined from tool steel and used to verify bore diameters in go-inspection applications. It measures 9.75 mm in diameter with a tolerance of 0.00508 mm and a surface finish of 10 microfinish, making it suitable for precise hole-acceptance checks. Each unit ships with a Certificate of Accuracy traceable to NIST, confirming the gage meets ASME B89.1 dimensional standards. The overall length is 2.0000 inches. Machinists, quality-control technicians, and metrology professionals use this gage as part of a standard go/no-go inspection routine on production or job-shop floors.

This plug gage is designed for go inspection of 9.75 mm bores and is also compatible with setup and verification tasks involving set micrometers, verniers, and other measuring devices. It suits both production environments and tool rooms where tight bore tolerances must be confirmed before components move to the next assembly stage. The compact form factor and tool steel construction make it a durable choice for high-cycle inspection work.

Key Features

• Class ZZ Plus tolerance grade with 0.00508 mm tolerance for precise bore acceptance
• Tool steel construction provides durability and resistance to wear during repeated use
• 10 microfinish surface finish supports consistent, repeatable contact measurements
• Includes Certificate of Accuracy with NIST traceability per ASME B89.1
• Suitable for go inspection, set micrometer setup, and vernier calibration tasks

Compatibility

Designed for go inspection of 9.75 mm diameter bores and for use with set micrometers, verniers, and other measuring devices as specified in the product application data.

Installation Notes

Plug gages are handled and used by metrology technicians and machinists; no power source or mechanical installation is required. Clean the gage and the bore thoroughly before use to prevent debris from affecting readings. Store in a protected case away from temperature extremes to maintain dimensional stability. Do not force the gage into an undersized bore, as this can damage both the gage and the workpiece.
